Ulysses Thomas was a captain in the 32nd Ossyrian Mechanized Infantry and he served with valor during the Fall of Ossyria. He was the commander of fireteam Hunter One in the second battalion "Warhorse". With a stoic attitude and a swift calculating mind, Ulysses led the fireteam through many tough and cruel missions with no casualties. Only two members of the team have died under his command, two deaths that plagued him where ever he went.

Ulysses Thomas was born in 59 AF to a teacher and a dentist in Ossyria. He was a shy child who had difficulty making friends preferring to sit by himself whenever possible. He was given the nickname "Iceman" in high school for being cold and uncaring to the many students and teachers around him. He attended the University of Dallas and graduated with a Master's degree in Engineering. Ulysses enlisted in the Ossyrian military to his parent's objection.

Already having a college degree, the Ossyrian military sent him to officer training school. Ulysses chose the new category, Human Military Vehicle, for his expertise and once he graduated with the rank of second lieutenant, Ulysses was placed in the 32nd Ossyrian Mechanized Infantry.
